IMPROVEMENT |N GATES.

Specification forining part of Letters Patent No. 200,514, datedFebruary 19, 1878; application filed January 12, 1878.

To all whom it may concern:

Be it known that we, SAMUEL CRIsTY and DAVID JAY, of Floris, in thecounty of Davis and the State of Iowa, have invented a new and valuableImprovement in Gate- Hinges; and We do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the,

in hinges for gates having a sliding and swinging movement.

The nature of our invention consists in a sliding and swinging gate, incombination with the spaced horizontal brackets, of thelongitudinally-slotted block having a bearing-roller and a lateralautifriction roller, as will be hereinafter more fully shown anddescribed.

Inthe annexed drawings, the letters A A designate the posts, and B agate, closing the gap between them. This gate is composed of the spacedlongitudinal rails to and uprights (H, at right angles thereto. 7

C O designate two spaced metallic brackets, extending out horizontallyand obliquely beyond the face of the post A, and provided at their freeends with bearings, in which are seated the journals i of an uprightsupporting-block, D. The brackets O G are preferably recessed, asregards their bases i, in the post A, and are secured thereto by meansof suitable bolts and nuts, or other appropriate means.

The block D rotates axially in its bearings,

and is longitudinally slotted, as shown at c,

Fig. 2. It is also made in two sections, cl d,

secured together by means of bolts 0. At the bottom of the slot 0 isplaced a pulley, f, rotating freely on the lower bolt 6, which joins thesections cl (1 together. This pulley supports the gate, one of therails, a of which extends through the slot 0 of the block D above saidpulley.

Each section of the supporting-block is provided with a verticalanti-friction roller, g, between which the rail alof the gate isreceived, the object of which is to facilitate the sliding movement ofthe gate, and to protect its bearing-rail a from abrasion during suchmovement.

The section of the block D has two projecting stay-arms, Z, one at eachside, which widen the bearing on the rail A, and give increased leverageand support to the gate when being opened.

In practice the anti-friction rollers y will be entirely shut in, so asto exclude dust, ice, and snow.

The sections of the block D being detachable from each other, therollers aforesaid may be readily removed when broken or worn out, andthe block may be readily applied to a gate without taking it apart.

What we claim as new, and desire to secure by Letters Patent, is- 1 In asliding and swinging gate, the combination, with the spaced horizontalbrackets O O, of the.longitudinally-slotted block'D, having thebearing-roller. f and the lateral antifriction rollers g, substantiallyas specified.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
